\"Snoopi,<\/a>

Snoopi, aka Prints, in his hoodie.<\/p><\/div>\n

Snoopi, aka Prints, will \u201csniff\u201d out data of people around him through a wearable hoodie controller that he will wear and display the information on a LED screen attached to the hoodie. This real time data and collected data would also be visualized in the \u201cdog house\u201d on a computer nearby.<\/p>\n

As a group, we have thought a lot about the way our data is collected on an everyday basis, with and without our knowledge. We are interested in exploring this topic and spotlighting this issue to people who may be unaware. Culturally we are at a place where the ramifications of having this data shouted out over wireless network has largely remained unseen. With Snoopi we want to start the conversation surrounding simple, benevolent acts (such as petting a dog) and data collection and profiling. Also we like puns.<\/p>\n

Sniffing Program<\/b><\/p>\n

We are using N.S.Heyy, created by Surya Mattu<\/a>, to pick up wifi signals from nearby mobile devices. This allows us to capture unique mac addresses and their corresponding wifi router connection history and their distance to the program (through signal power).<\/p>\n

Snoopi Hoodie Display<\/b><\/p>\n

Prints will be wearing a hoodie controller with a LED screen attached on the back to display scrolling router history information. The LED screen would either be programmed by an Arduino which is connected to Bluetooth through BlueFruit or a mini computer such as the Raspberry Pi or Android device. The LED screen will display the information when the hoodie is up and not display anything when the hoodie is down. This would be done with conductive material sew on the hoodie to create an on\/off switch.<\/p>\n

Data Visualization (dog house)<\/b><\/p>\n

The data visualization is a Processing sketch that would run on a nearby computer. It would display the people\/devices around Prince in real time. Viewer would be able to click on each to reveal their router history. The dominant router names sniffed from the area would also be displayed in the corner of the visualization.<\/p>\n
